In addition to testing the strike range of the rotary cannon, the second phase of testing will also test the fire coverage and the impact of the recoil generated by the cannon when firing on the drone.
Because the caliber of the machine gun bullet reaches 14.7mm, the recoil generated when firing became one of the biggest difficulties Xu Jianguo faced when designing this drone and external components.
To this end, Xu Jianguo tried countless methods and finally chose to reduce the impact of recoil on the flight posture of the drone by installing a muzzle brake at the muzzle and a hydraulic shock absorber behind the barrel.
It is precisely because of the addition of these two accessories that the magazine capacity of the machine gun can only be controlled within 6,000 rounds.
As the drone flew to the designated firing area and hovered, Xu Jianguo picked up the intercom and said, "The first round of the second phase of the Tianfa 001 attack drone test begins now!"
At this time, the target is one kilometer away from the drone. Xu Jianguo will control the drone to conduct tests at positions of 1000 meters, 800 meters, 600 meters and 400 meters respectively.
While testing the effect of recoil on the drone, it is also necessary to examine the effect of distance on shooting accuracy.
As the sound of "received" came from the walkie-talkie, Xu Jianguo turned on the drone's fire control switch with his left index finger, and then a cross cursor similar to a sniper rifle scope appeared on the display.
Xu Jianguo used his left index finger to turn the zoom ring, and the cursor quickly zoomed in and soon aimed at one of the targets a kilometer away.
Then he pressed the fire button with his right index finger, and saw the No. 001 drone in the sky suddenly spew out a one-meter-long tongue of fire.
In the blink of an eye, a cloud of dust rose up at the location of one of the targets on the gentle slope of the distant hill.
After Xu Jianguo pressed the fire button for about three seconds, he released his right index finger and turned off the fire control switch.
"Report the target!" Liu Mingyu, who was standing by, grabbed the walkie-talkie and shouted.
Immediately afterwards, the shadows of two jeeps appeared at the foot of the mountain, speeding towards the gentle slope where the target was located.
